Title: Reproducing apparatus
Inventor: HAGA TAKENORI
IPC: H04S3/00
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To automatically execute settings between channels and to prevent malfunctions by outputting signals of a plurality of channels, detecting that a line is connected to an output terminal and adding the signal of a channel whose connection is not detection means to the signal of a channel, which is outputted to the output means for detecting that the line has been connected. SOLUTION: A microcomputer 17 detects whether a load is connected to an output terminal with the voltage of contact points 24-29 and displays whether the load is connected or not in output terminals 18-23 on a display part 31. It displays non-connection channel or/and output terminals on the display unit 31 for a prescribed period. If load is not connected to the output terminal 20 of an SL signal or the output terminal of an SR signal and a channel signal is in a non-output state, the microcomputer 17 discriminates from the voltage of contact points 26 and 27, adds the SL and SR signals to FT and FR signals, and they are outputted. Thus, switches 10 and 11 are turned on, and the SL and SR signals are outputted to adders 14a and 14b.

Title: Apparatus and method for conduction control
Inventor: EGUCHI YASUHITO
IPC: H02J7/00
Filed: 1999-02-12
Abstract: PROBLEM TO BE SOLVED: To supply discharge current from a battery pack to a personal computer with little loss. SOLUTION: When an FET 61 is in a tamed off state, the discharge current from a battery pack 52 flows from a drain to a source via a parasitic diode 61A. The voltage between the source and drain, Vdrop , attempts by feedback to hold at the same potential using a voltage drop VR155 at a resistor 155 as a reference voltage. Since the voltage drop VR155 at the resistor 155 is sufficiently lower than a voltage drop VF61 of the parasitic diode 61A, the voltage between the source and drain Vdrop can be made sufficiently smaller than the voltage drop VF61 .

Title: Frequency multiplying circuit
Inventor: TAKANO HISAO
IPC: H03B19/00
Filed: 1981-03-10
Abstract: PURPOSE:To achieve low frequency multiplication by latching the count value of high-frequency clock pulses by pulses which synchronize with an input basic signal, and comparing this value with the count value of another counter which counts the clock pulses. CONSTITUTION:A synchronizing pulse generation part 2 receives an input basic signal SS and generates latch pulses LP and counter controlling pulses CC cynchronizing with the input signal. A clock pulse generation part 3 generates and inputs pulses CP having a much higher frequency than the SS to counters 4 and 7. A latch 5 latches a value a quarter as great as a count value right before the counter 4 is reset at the timing of the pulses LP. The value of the latch 5 and that of the counter 7 are compared mutually by a comparator CP6 and when the two become equal to each other, the CP6 outputs a pulse MP, which resets the counter 7, thus repeating the counting of the counter 7. The value of the pulse MP is halved by an FF8 to output a rectanglar wave, which is passed through a BPF8 to output a sine wave.

Filed: 1980-03-18
Abstract: PURPOSE: To reduce the decrease in the capacity of an air conditioner etc. and make the compressor smaller in size by inserting a strainer of special construction to the front of the gas suction port of a compressiong chamber.  
     CONSTITUTION: A metallic screen 7 formed to a bas shape is inserted into the wire metals 6 wound spirally, to form a strainer. This is inserted to the front of the suction port 5 of a compression chamber to remove dust. The area of the metallic screen grating is defined as S and the number of the strainer gratings before the suction port 5 of the case when no metallic wires 6 are inserted is defined as n 1  piece. If the number of the gratings of the strainer before the suction port 5 of the case when the metallic wires 6 are inserted is defined as n 2  piece, these are n 2 >n 1 . If the area having no metal wires 6 out of the strainer area before the suction port where gaseous flow is defined as Sx and the area having no metallic wires 6 as Sy, the equations holds. The insertion of the metallic wires 6 leads to the widened flow passage area of the time when the gas passes the strainer and the decreased pressure drop of the gap.

Title: Quadruple-phase angle modulation wave delay detector
Inventor: KUBO KAZUTOSHI
IPC: H04L27/227
Filed: 1989-02-14
Abstract: PURPOSE:To reduce a circuit scale by calculating a phase difference between two consecutive symbols from a digital signal of a reception signal, correcting phase rotation due to a frequency offset and applying delay detection by a digital signal processing. CONSTITUTION:A quadruple phase-shift keying(Q-PSK) signal has 4 cases of 0 deg., 90 deg., 180 deg., 270 deg. in a phase difference between two consecutive symbols. Then the signal of the in phase component and the orthogonal component of the initial symbol is used as a reference vector, the signals are rotated by 90 deg. each to prepare 4 reference vectors. Since the phase of the symbol is rotated by the frequency offset, it is corrected and inner product is taken with the 4 reference vectors. As a result, the reference vector phase taking a maximum value represents the phase difference between the two symbols and the inner product between the reference vector adjacent to the reference vector taking the maximum value and the next correct symbol represents the level of the frequency offset. Thus, the delay detection is implemented with a simple construction.

Title: Polarization inversion control method
Inventor: KIJIMA KOUICHIROU
IPC: G02F1/377
Filed: 1991-02-28
Abstract: PURPOSE:To securely generate the polarization inversion of a fine pattern with good controllability by irradiating a ferroelectric material with charged particles to plural areas at intervals which are large enough to exert no mutual influence on each other. CONSTITUTION:The areas on the singly polarized ferroelectric material 1 are irradiated locally with the charged particles to form a polarization inversion structure 3. The areas are irradiate with the charged particles at the intervals LB where no mutual influence is exerted. Thus, interference between adjacent irradiated areas is evaded and polarization inversion 3A can be generated independently. After the areas are irradiated with the charged particles at said intervals LB where no mutual influence is exerted, accumulated charges on the ferroelectric material 1 are removed and other areas nearby the irradiated areas where an electric field is removed are irradiated with charged particles while the intervals LB are maintained to generate each polarization inversion 3A independently.

Then a DC winding which is in-phase antiparallel-connected so that electric currents of the same quantity can flow in opposite directions between a pair of connecting conductors 21 paired to each phase is formed by connecting the split windings with two sets of three-phase windings having opposite phases by means of U-shaped interphase connecting conductors 11 connected to the transformer-side terminal row 17 and connecting one ends of the conductors 11 between facing terminals of both terminal rows 17 and 27 by means of the conductors 21 which are extended toward the terminal row 17.

Abstract: PURPOSE:To prevent the generation of flaws and stains on a high-polymer film by sticking a surface protective film on the opposite face of the high- polymer film having a conductive film on one face, tentatively fixing the same to a plate and etching the conductive film. CONSTITUTION:The thin conductive film consisting of a metal such as Ag, Cu or Al or metallic oxide such as SnO or In2O3 is deposited by a vacuum deposition method on one face of the high-polymer film consisting of a polystyrene, polymethyl acrylate, PVC, etc., as a substrate. A photosensitive film resist mask of a water soluble treatment type is formed on such thin film and the protective film consisting of a PE film and acrylic self-adhesive agent is formed on the opposite surface of the high-polymer film. The photosensitive film resist mask is exposed with a desired pattern and thereafter, the protective film surface is fixed to the surface of the plate material. The resist mask in the unexposed part is dissolved and the film is etched. The resist film on the remaining surface is stripped and the film of the conductive pattern having no flaws and stains is thus formed on the high-polymer film.
